Aftermarket Wheels & Tires for 2007 Infinity G35 Sport Sedan???

[07G35SPT]

Hello all. Maybe someone out there might be able to help me with a wheel and tire question. I have just recently purchased a 2007 Infinity G35 Sport Sedan and I am looking for some aftermarket wheels and tires. I would like to hear from some people that have already fit-up a wheel/tire package to this vehicle. The stock wheels and tires are: Front = 7.5" x 18" wheel and 225/50R18 95W Bridgestone Potenza RE050A tire. The Rear = 8.5' x 18" wheel and 245/45R18 96W Bridgestone Potenza RE050A tire. F&R bolt pattern = 5 x 114.3. I believe the lugs are 12 x 1.25 pitch (2006?) I don't know what the stock wheel offset is. What I am looking at for wheels and tires is: MRR Design Wheels.(www.mrrwheels.com). I want to use the GT-1 "Black". Front size would be 8.5" x 19" (1 in/up) with a 35 offset and a 245/40R19 tire and the rear would be a 9.5" x 19" (1 in/up) with a 45 offset and a 275/35R19 tire. This combination would increase the width of the tires, F&R, by .5" inside and outside. Would this work with the stated offsets? Would there be proper clearance to the fenders and brake assembly? Would these tires mount up to these wheels? Has anyone out there actually tried this combination on a 2007 G35 Sport Sedan yet? Any help would be greatly appreciated before I order this wheel/tire combination.

I'm thinking of doing something similar with my '07. Have you purchased these yet? There are some good offset web sites. Try this: http://www.1010tires.com/WheelOffsetCalculator.asp I have a Journey not an S so I don't have the brake issue. I believe the S has Brembo's.

If you have purchased please share photos with the rest of us. I'm struggling with what to purchase. I want chrome adn these look nice. Not enough photos out there yet...

I've been told 275's will work. BTW
